Health officials announced Wednesday that three human cases of West Nile virus have been detected in New York City. Of the three infected, two were in Queens and one in Manhattan. A fourth possible case is being investigated on Staten Island.  
“We are working to prevent West Nile as much as possible through public education, treating marshy areas and spraying for mosquitoes,” the city’s Health Commissioner Dr. Ashwin Vasan said in a news release

Dr. Vasan says New Yorkers can take several precautions to prevent getting infected by the mosquito-borne illness such as using insect repellent, especially at dusk and dawn when the insects responsible for transmitting the virus are most active. He also recommends emptying out any containers that hold standing water to prevent the mosquitoes from laying eggs. If a person sees standing water, they should call 311.

The New York City Department of Health also lists several other ways to reduce risk.
  • Make sure windows have screens. Repair or replace screens that have tears or holes.
  • Make sure roof gutters are clean and drained properly.
  • Clean and chlorinate swimming pools, outdoor saunas, and hot tubs. Keep them empty or covered if not in use.
  • Drain water that collects in pool covers.
  • People with compromised immune systems should remain indoors when mosquito activity is highest.

What Is West Nile Virus?

According to the Centers for Disease Control and Prevention, West Nile virus is the leading cause of mosquito-borne disease in the United States. It spreads to people when they are bitten by an infected mosquito.
Cases are highest during mosquito season, which runs from summer through the end of fall with activity peaking in August and September. Currently, no vaccine to prevent or medications to treat the infection exist. Most people are said to have no symptoms and are thus unaware they have it. The agency approximates just one in five people will develop symptoms such as headache, fever, body aches, joint pain, vomiting, diarrhea, or rash. One out of every 150 people will develop a serious illness that can lead to death.

History of West Nile in New York City

West Nile virus was first detected in New York City more than 20 years ago. An estimated 17 people ranging from 22 to 95 years old have been infected per year over the past decade. Ten percent of those cases resulted in death.

“The Health Department has successfully helped control mosquito-borne diseases since West Nile virus was first detected. The agency’s comprehensive, data-driven approach to mosquito control efforts relies on mosquito trapping and testing results to determine areas of the city to spray pesticide and apply larvicide by helicopter, truck or backpacks,” according to the news release.
